First make sure that you have good battery in the key.

This may not work - but for my S500. To restore the factory settings you press the lock and unlock buttons simultaneously for about 6 seconds until the battery check lamp flashes twice.

If not - does anyone here have a similar vintage G500 who also still has a handbook? Should be instructions in there as to how to reprogram key fob.

Just had a quick Google and there appear to be lots of different solutions but for different models/ model years.

Re: Re Programe Keys

What type of key do you have? The IR type without blade? If so, does it fail to start the engine or are you referring to the central locking?

The former (no engine start) is typically either a failure of the EIS module or you've dropped the fob too many times and the transceiver coil has detached from the small circuit board in the keyfob.

As for door cards, yes they are all interchangeable, except for the latest versions (2015 onwards), where they have added extra switches in the group for the seat adjustment switches, on the front  door cards.

IF I'm not mistaken a 1999 G would have the old 1-button rectangular fob, for which these instructions might help:
